Reverse: 1999's Version 3.4, titled Spring Unending, is the game's 2.5th Anniversary update and it arrives with more free currency than any recent patch. Between the 100 free summons banner, daily login rewards, a new 6-star character in Paper Heron, Euphoria upgrades for four characters, and half a dozen parallel events, there's a lot to track. This guide breaks down every active system so you can prioritize your time and pull currency without missing anything.
Paper Heron's limited banner
What free summons are available in Version 3.4?
The headline offer is The Snow of Dushuo, a 100-pull banner running from April 4 to May 28, 2026 (UTC-5). Log in daily and you receive 10 free summons per day, up to 10 days total. Before you start pulling, select and lock one 6-star character from the designated pool as your personal rate-up. The pool includes An-an Lee, Voyager, Regulus, Tooth Fairy, Barcarola, Isolde, Eternity, Semmelweis, Medicine Pocket, Marcus, Getian, Vila, Sotheby, Argus, Jessica, Willow, Noire, A Knight, and Corvus.
The guaranteed count on this banner is independent and does not carry over after the event closes, so use all 100 pulls before May 28.
Pick your rate-up character before pulling a single time. The selection can be changed, but locking it in early avoids accidental pulls on a character you already own.
Separately, the 2.5th Anniversary login event also gives Unilog x20 total across two sign-in periods (Spring Unending I and II), each requiring 10 login days. That's on top of a free Decatone (10-pull ticket) for the Her Heart-Cut Spring banner just for logging in after the April 16 update.
Which banners are running and when do they end?
Version 3.4 has more simultaneous banners than usual. Here's a breakdown of every active summon event, according to the official patch notes:
Her Heart-Cut Spring uses an independent pity counter that clears after the event. Every pull on it earns one Cassette of the Lost, and spending 200 Cassettes at the Limited Shop guarantees Paper Heron directly.
Ripples on the Water is the most player-friendly standard banner: the first 6-star is guaranteed to be your selected character, subsequent ones have a 50% chance, and the pity counter carries over to future Ripples banners. The first 10-pull costs only 7 Unilogs instead of the usual 10.
Revelation of the Water lets you select two 6-stars for rate-up simultaneously, with a 70% chance per 6-star pull to land one of your picks. The first 10-pull here costs 5 Unilogs.
Dushuo Festival Limited Banner pity does NOT carry over after May 28. If you're close to the 200 Cassettes threshold, prioritize finishing before the shop closes.
Select your rate-up character
What is the Spring Unending main event and how do you farm Windborne Whisper?
Spring Unending is the primary story event for Version 3.4. The story mode runs until May 25, and the event shop stays open until May 28. To access it, you need to have completed main story chapter 1ST-16 (Heaven Apostles).
Completing story stages and challenges earns Windborne Whisper, the event currency. The Editor's To-Do List tasks also award Windborne Whisper throughout the event period.
The event shop, Legacy of the White Horse, is where you spend it. Priority purchases include:
- Immaterial Photoscope (requires 3 Immaterial Batteries to open; lets you select one 6-star Artifice from a designated group)
- New 6-Star Psychube: Wayfarer of the Dao
- Gluttony, Crystal Casket, Unilog
- Advanced Insight and Resonance Materials
- Vision Blocks, Old Ticket, Dust, Sharpodonty
The Immaterial Photoscope designated group for this event covers 6, Tooth Fairy, Willow, Druvis III, Lilya, Sotheby, Eternity, Ms. NewBabel, Jessica, Shamane, and Voyager. If any of those characters need an Artifice upgrade, this is a strong pull.
Cassettes of the Lost expire when the Limited Shop closes. Immaterial Batteries acquired through login events can be used to open the Photoscope, but confirm you have 3 before spending them.
Which characters are getting Euphoria upgrades in Version 3.4?
The Euphoria Character Enhancement System is expanding in this update. Four characters receive Euphoria in Version 3.4: Tooth Fairy, Liang Yue, 6, and Willow. The eligibility requirement is Insight III Level 30 for 6-star characters and Insight III Level 1 for 5-star characters, plus completion of main story 1ST-16.
Two new Photomancy characters are also added this patch: Tooth Fairy and A Knight.
For context, Version 3.3 added Euphoria for An-an Lee and Mercuria, so if you're building those characters, that system is already live.
